1. Scope

1.1 Objective

This standard operating procedure is intended to provide operating

instructions and safety information for the Department of Mechanical

Engineering’s Rover Gas Turbine experiment apparatus located in H-17,

Head Hall. This document is intended as a guideline and supplement to

proper training that must be provided by qualified personnel before the

apparatus is operated. The aim of this document is to ensure that safe work

practices have been developed for the Rover Gas Turbine experimental

work. This SOP is primarily concerned with the operating procedure of the

apparatus, hazards involved in the experiment and safety precautions that

must be taken to avoid injuries.

1.2 Regulations

This document has been developed in accordance with the Environmental

Health and Safety Office of the University of New Brunswick.

2. Apparatus Overview and Objective

2.1 Apparatus overview

The experimental apparatus admits ambient air through two sideways air

intakes into the compressor housing. There is an airmeter thermometer

mounted on the intake of airmeter to measure the temperature of air being

pulled in to the IS/60 engine. The Airmeter has a 4.5 inches diameter venturi

in it for computation of the air mass flow. The compressor in the

compressor housing is a single stage centrifugal pump and consists of a 17

guide vanes impeller machined from an aluminum alloy forging. The vanes

of the impeller have curved leading edges to assist air entry into the eye of

the impeller. The air is then pumped by the blades of the impeller to the

reverse flow combustion chamber of the IS/60 engine. The combustion

chamber consists of an igniter plug which is connected to a battery via an

igniter box and a keyed ignition. When the starter key is turned clockwise

position) on the keyed ignition, the engine starts up with the compressor

pumping air into the combustion chamber and out of the apparatus through

exhaust. The engine is running on battery power until it reaches a constant

RPM of about 4000 RPM, then the fuel operating lever is opened and the

igniter plug on combustion chamber produces sparks which in turn start the

combustion of air/fuel mixture in the combustion chamber.
